Cervical angioleiomyoma

Uterine Cervical Angioleiomyoma Mimicking Squamous Cell Carcinoma

Angioleiomyoma, a rare variant of leiomyoma, is a benign tumor of mesenchymal origin. Angioleiomyomas of the female urogenital tract are extremely rare, with only six cases of uterine cervical angioleiomyoma previously reported in the literature. In this case study, we report on a 49-year-old female patient who presented with menorrhagia whose initial magnetic resonance imaging (MRI) findings suggested cervical squamous cell carcinoma (SCC). However, following the hysterectomy, histological examination confirmed the lesion to be angioleiomyoma. To the best of our knowledge, there have been no previously reported cases of angioleiomyomas presenting with MRI findings that are suggestive of uterine SCC. Recognizing that angioleiomyomas can mimic uterine malignancies on MRI may prove beneficial for future diagnostic and treatment strategies.

Angioleiomyoma of Uterus and Cervix: A Rare Report of Two Cases

We report two rare cases of genital angioleiomyomas (ALs), one each of uterus and cervix. The uterine AL showed a very rare presentation of endometrial polyp, while the cervical AL presented as an intramural cervical growth. We have also reviewed the literature and enlisted all uterine and cervical ALs reported till now.

A giant superinfected uterine angioleiomyoma with distant septic metastases: an extremely rare presentation of a benign process and a systematic review of the literature

PURPOSE

Uterine angioleiomyoma is a rare type of leiomyoma variant and there are few cases reported in the literature. The definitive diagnosis is usually obtained only after the histopathologic examination because there are no specific imaging criteria for this disease. The objective of this article is to review published cases about this clinical condition.

METHODS

We report a case of giant angioleiomyoma superinfected by S. agalactiae with the development of latero-cervical distant metastasis in a premenopausal woman. Firstly, the case herein reported was orientated as an endometrial stroma sarcoma in the peri-operative histologic examination by frozen sections. It was treated with laparotomic total hysterectomy, bilateral salpingo-oophorectomy, inframesocolic omentectomy and pelvic and paraaortic lymph node dissection. Postoperative definitive anatomopathological analyses using a proper immunohistochemical panel revealed a case of uterine angioleiomyoma. We also review other case reports published about this clinical condition.

RESULTS

We present the first case reported in the literature, in our knowledge, of a giant angioleiomyoma superinfected by S. agalactiae with the development of distant septic metastases. Immunohistochemistry permitted the definitive diagnosis of angioleiomyoma. Treatments previously reported are hysterectomy or tumor resection and any patient recurred.

CONCLUSIONS

The definitive diagnosis is usually obtained after the definitive histopathologic examination since the use of immunohistochemical study has an important role in this regard. Complete surgical removal of the lesion is the treatment of choice, with no recurrent cases reported to date.

Angioleiomyoma of Uterus: A Clinicopathologic Study of 6 Cases

BACKGROUND AND OBJECTIVES

Angioleiomyoma is a benign perivascular neoplasm commonly involving subcutaneous tissue of extremities, head, and trunk region. They rarely involve the female genital tract. This study analyses clinicopathological features of 6 cases of uterine angioleiomyoma.

METHODS

Routine sections of 6 cases were reviewed and immunohistochemical markers namely muscle-specific actin, h-caldesmon, desmin, CD10, WT-1, HMB-45, and melan-A were done.

RESULTS

Of the 6 cases, 4 cases had tumor involving the corpus and 2 cases had tumor in the cervix. Grossly, all tumors had a whorled and congested cut surface. Microscopic examination of all the cases revealed circumscribed neoplasms composed of interlacing fascicles of benign perivascular smooth muscle cells with evenly distributed slit-like blood vessels (solid variant) along with vessels exhibiting thick muscular walls with swirling pattern (venous variant). In only 2 cases many dilated vessels were seen (cavernous variant). Immunohistochemically, all cases were positive for muscle-specific actin, h-caldesmon, and desmin. All cases were negative for CD10 and WT-1 ruling out endometrial stromal tumor and were negative for HMB-45 and melan-A ruling out perivascular epithelioid cell tumor (both endometrial stromal tumor and perivascular epithelioid cell tumor have prominent vessels but have different histomorphology). In all cases, surgical excision was curative and there were no intraoperative or postoperative complications. Follow-up of all the cases has been unremarkable.

CONCLUSION

As the World Health Organization has not included angioleiomyoma in the classification of mesenchymal tumors of uterine corpus and cervix, we recommend that it should be included in the classification.

Uterine angioleiomyoma - a rare variant of uterine leiomyoma: review of literature and case reports

Introduction

Uterine angioleiomyoma (AL) is an extremely rare variant of uterine leiomyoma. It is composed of smooth muscle cells and thick-walled blood vessels. Angioleiomyoma usually occurs in middle-aged women, 40-60 years old. Aim of the study was to review of literature research reports on uterine AL. Discussion of nine case reports of uterine AL in the patients operated on in our ward.

Material and methods

The paper presents analysis of accessible research reports on uterine AL, and medical records of the patients operated on in our ward.

Results

Mean age of the patients with uterine AL was 47.11 ±5.21, body mass index (BMI) 25.88 ±3.95. All women had given birth (1-5 natural deliveries, 2.44 mean). Uterine AL occurred in 0.34% to 0.40% cases of leiomyomas. Angioleiomyoma were located intramurally and subserosally in six and three patients (respectively, 66.7% and 33.3%). Laparotomy was undertaken in seven cases (77.8%), transvaginal access in two cases (22.2%), and myomectomy in one case (11.1%). Blood transfusion was required in four cases (44.4%).

Conclusions

In the group of uterine leiomyomas, uterine ALs occurred in 0.34-0.40% of cases. Angioleiomyoma cases posed a greater risk of complications threatening the patient’s health and life. Preoperative differentiation of AL with ovarian tumour was more difficult due to frequent degenerative lesions in the course of uterine AL.
